Mac OS X Lion Release Date & Price?

What is the release date and price of Apple's new Mac OS X Lion?
The company said the release date was around July and we're about to enter the second half of he month and no info has been revealed yet.
I'm very interested about the price. Is it going to be available the same day the announce it on the Apple store?
Do you think they're going to make us wait even more for Mac OS X Lion?

Mac OS X Lion 10.7 is coming soon, Apple said it will be available this month.
Besides the operating system, it is rumored they are also going to release a new Macbook Air and Macbook Pro models.
The new hardware won't arrive before the iOS 5 update, but chances are that they will break cover at the same time.
Mac OS X Lion will be releasing solely through the Mac App Store as a digital download and the price is $30.
